The shift supervisor of a pizza parlor claimed that the population mean total time to deliver a pizza is exactly 45 minutes. Paige, the owner, would like to find evidence that the population mean total time to deliver a pizza is less than 45 minutes so she records the total delivery time of 71 randomly selected deliveries and she finds that the sample mean is 44.06 minutes with a sample standard deviation of 3.46 minutes. The test statistic t for a hypothesis test of H0:μ=45 versus Ha:μ<45 is t≈−2.29. If 0.01a. Reject he null hypothesis that the true population mean total time to deliver a pizza is equal to 45 minutes. b. Fail to reject the null hypothesis that the true population mean total time to deliver a pizza is equal to 45 minutes. c. There s not enough evidence at the r = 0.05 level of significance to suggest that the true population mean total time to deliver a pizza is not equal to 45 minutes. d. There is enough evidence at the a 005 level of significance to support the claim that the true population total time to deliver a pizza is less than 45 minutes

A soft drink company has recently received customer complaints about its one-liter-sized soft drink products. Customers have been claiming that the one-liter-sized products contain less than one liter of soft drink. The company has decided to investigate the problem. According to the company records, when there is no malfunctioning in the beverage dispensing unit, the bottles contain 1.01 liters of beverage on average, with a standard deviation of .13 liters. A sample of 70 bottles has been taken to be measured from the beverage dispensing lot. The mean amount of beverage in these 70 bottles was 0.993 liters. Find the probability of observing a sample mean of 0.993 liters or less in a sample of 70 bottles, if the beverage dispensing unit functions properly. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.

Harry had $32. He spent all the money on buying 3 notebooks for $x each and 4 packs of index cards for $y each. If Harry had bought 5 notebooks and 5 packs of index cards, he would have run short of $18. A student concluded that the price of each notebook is $5 and the price of each pack of index cards is $1. Which statement best justifies whether the student's conclusion is correct or incorrect?a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).b. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (8, 2).c. The student's conclusion is correct because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (5, 1).d. The student's conclusion is correct because the solution to the system of equations 3x − 4y = 32 and 5x − 5y = 50 is (5, 1).
